Good day. I am sorting through the wiring before I actually modify harness. The GM service manual on page 8-346 schematic specs that for standard gas engine the fuel level comes in on C152-K, and C152-D for L59 Flex. On page 6-2398 the schematic is C152-D is Fuel press sensor but no alternate for L59. Is this a misprint or I'm reading the schematic wrong. The manual is 2006 Silverado GMT/06-CK8PU. If someone can verify this for me and what is correct that would be great.

Thanks
Thad
